Abstract

Nap-of-the-Earth (NOE) flight and the development of advanced Unmanned Air Vehicles (UAV) require further integration of sensors and onboard processing. Flying insects feature a panoramic eye which relies on Optical Flow (OF) for guidance and obstacle avoidance. We describe the development of a miniature thrust-vectoring UAV fear turing an analog electronic eye based on biological motion detection. The system is tested within the laboratory on a custom-built whirling-arm rig. Preliminary tests have demonstrated satisfactory maneuvrability under remote-control. The project combines the fields of neurobiology, robotics, and aerospace. A VLSI implementation of the vision system is planned.
